Hello my friends I need your help. I'm learning to use the AWS console, so I'm using the free version for 12 months. However, I had a cost for the platform's mysql database, so I deleted the database instance, the automatic backups and also the snapshots, but when I went to delete the group parameters, the error below occurs:

Failed to delete default.mysql8.0: Default DBParameterGroup cannot be deleted: default.mysql8.0 (Service: AmazonRDS; Status Code: 400; Error Code: InvalidDBParameterGroupState; Request ID: cec752fc-6e77-4a42-b38b-c26b079a6e21; Proxy: null).

With this I have the following doubts: How can I delete this group of parameters? As I deleted the database instance, automatic backups and snapshots, will I continue to have a cost on the platform?

Thanks

I deleted the DB instance, automatic backups and snapshots. I tried to delete the group parameters and the error occurred

If you create a DB instance without specifying a DB parameter group, the DB instance will use the default parameter group for the DB engine.

You cannot delete a default parameter group. This is specified in the AWS docs documentation for the DeleteDBParameterGroup action.

Parameter groups cost no money.

You probably trying to delete something default and parameter groups can not create cost for your account, dont worry. If you share your error and configuration with pictures, I can help you.
